Abstract

Techniques for mesh augmentation and prevention of incisional hernia, including systems and methods for affixing mesh to a fascial incision. A mesh strip can be integrated with one or more uni-directional fasteners. Each fastener can include an anchoring mechanism adapted for affixation to anterior abdominal wall fascia and a mating interface. An applicator can include tension arms adapted to interface with the mating interfaces of the fasteners to maintain a vertical tension of the mesh strip and a handle coupled with the tension arms adapted to spread the tension arms and thereby control a horizontal tension of the mesh strip. The mesh strip can be configured to be aligned over a fascial incision using the applicator and affixed under tension to anterior abdominal wall fascia by tissue penetration of the anchoring mechanisms of the one or more fasteners.

First claim

The invention claimed is:

1. A system for affixing mesh to a fascial incision, comprising:
a mesh strip pre-integrated with one or more uni-directional fasteners prior to application of horizontal tension, each fastener including an anchoring mechanism adapted for affixation to an anterior abdominal wall fascia and a mating interface;
an applicator comprising tension arms adapted to interface with the mating interfaces of the fasteners to maintain a vertical tension of the mesh strip and a handle coupled with the tension arms adapted to spread the tension arms and thereby control the horizontal tension of the mesh strip through the interface between the tension arms and the mating interfaces of the fasteners from contact between the mesh strip and the fasteners; and
wherein the mesh strip is configured to be aligned over a fascial incision using the applicator and affixed under tension to the anterior abdominal wall fascia by tissue penetration of the anchoring mechanisms of the one or more fasteners.

2. The system of claim 1 , further comprising a tray adapted to hold the mesh strip prior to interfacing with the applicator, wherein the tray includes wells adapted to interface with the anchoring mechanisms of the one or more fasteners and support the mesh strip and fasteners during mating with the applicator.

3. The system of claim 1 , wherein the applicator further comprises a tensiometer configured to measure and display the horizontal tension of the mesh strip.

4. The system of claim 1 , wherein the applicator further comprises a spring to facilitate out of plane affixation of the mesh strip to the fascia.

5. The system of claim 4 , wherein the applicator has an omega shape, wherein the handle of the applicator comprises the spring.

6. The system of claim 1 , wherein the applicator further comprises an electro-mechanical actuator to affix the one or more fasteners and the mesh strip to the fascia.

7. The system of claim 1 , wherein the mating interfaces of the one or more fasteners include one or more of: a post or a knob adapted to be received by a port of at least one of the tension arms, or a snap or a structural element having a hole therein adapted to receive at least one of the tension arms.

8. The system of claim 1 , comprising a spring-loaded advancement function for synchronized deployment of the one or more fasteners.

9. A system for tissue reinforcement, comprising:
a planar construct pre-integrated with one or more fasteners to application of horizontal tension, each fastener including an anchor adapted for affixation to tissue and a mating interface;
an applicator comprising tension arms adapted to interface with the mating interfaces of the fasteners to maintain a vertical tension of the planar construct and a handle coupled with the tension arms adapted to spread the tension arms and thereby control the horizontal tension of the planar construct through the interface between the tension arms and the mating interfaces of the fasteners from contact between the mesh strip and the fasteners; and
wherein the planar construct is configured to be aligned over an area of tissue using the applicator and affixed under tension by tissue penetration of the anchors of the one or more fasteners.

10. The system of claim 9 , wherein the planar construct comprises a mesh.

11. The system of claim 9 , wherein the planar construct comprises tissue.
